Abstract

The Point-to-Point Protocol (PPP) [1] provides a standard method of encapsulating Network Layer protocol information over point-to-point links. PPP also defines an extensible Link Control Protocol, and proposes a family of Network Control Protocols (NCPs) for establishing and configuring different network-layer protocols.

1. Introduction

PPP has three main components:

1. A method for encapsulating datagrams over serial links.

2. A Link Control Protocol (LCP) for establishing, configuring,

and testing the data-link connection.

3. A family of Network Control Protocols (NCPs) for establishing

and configuring different network-layer protocols.

In order to establish communications over a point-to-point link, each

end of the PPP link must first send LCP packets to configure and test

the data link. After the link has been established and optional

facilities have been negotiated as needed by the LCP, PPP must send

NCP packets to choose and configure one or more network-layer

protocols. Once each of the chosen network-layer protocols has been

configured, datagrams from eac...
